IMPROVEMENT IN STOVE-PIPE SHELVES.

Specification forming part of Letters Patent No. 204.570, dated June 4,1878; application filed December 14, 1877.

To all whom 'it may concern:

Be it known that I, WILLIAM L. HEss, of Belle Plaine, in the county ofBenton and State of Iowa, have invented certain new and usefulImprovements in Stove-Pipe Shelves; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, which willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and toletters of reference marked thereon, which form a part of thisspecification, and in which- Figure 1 is a plan view of my stove-pipeheater or shelf. Fig. 2 is a vertical section thereof. Fig. 3 is adetached perspective view of the tubular valve or cut-oil for cuttingoff the passage of heat to the shelf.

Corresponding parts in the several figures are denoted by like letters.

This invention relates to certain improvements in stove-pipe heaters orshelves; and it consists in the employment, in connection with a drum orcylinder having ahorizontallydividing perforated partition andpipe-passage valve or damper, of a tubular valve opening and closing theupper and lower chambers of the said divided drum or cylinder,substantially as hereinafter more particularly set forth.

In the annexed drawings, A refers to a cylinder or drum, made preferablytapering upon its lower side, and adapted for attachment to a stove-pipeand stove. This cylinder or drum is divided horizontally by a partitionor diaphragm, B, having a series of marginal perforations or apertures,b b, for the passage of heat or hot air from its lower chamber into itsupper one. The top and bottom of this cylinder may be provided withisinglass-covered openings, if desired, and in one side is placed aslide or door, 0, through which it may be cleaned.

O is a tubular valve, operated by a headed projection, d, projectingthrough an inverted L-shaped slot in a pipe-connection, 6, upon theupper side of the cylinder. This valve fits within the passage in thecylinder between the stove and the stove-pipe, and is provided upon oneside with a lower opening, f, and upon its opposite side with an upperopening, f, the office of which is to open and close the lower and upperchambers of the divided cylinder when desired.

In the same passage, and within the tubular valve, but in no wayconnected with it, (the valve,) is a valve or damper, g g, to cut offthe direct passage of the heat or hot air to the pipe when it is desiredto direct it into the cylinder or drum. Affixed to one side of this drumis a shelf, h, to which may be temporarily removed from the drum theheated dish or dishes.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

1. In a stove-pipe drum having a horizontally dividing perforatedpartition and a valve or damper, the tubular valve 0, having the upperand lower openings ff, substantially as and for the purpose set forth.

2. The combination of the drum A, perforated partition B, dividing thesaid drum horizontally, damper g g, and tubular valve 0 ff,substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my own I hereunto affix mysignature in presence of two witnesses.

W. L. HESS.
